T60 Core Duo --> Core 2 Duo

spt60 · **Posted:** Thu Apr 05, 2007 2:20 pm

Would it be possible if I can upgrade my T60 older version with the Core Duo to Core 2 Duo CPU? They do need different motherboards don't they?

Thanks,

As far as I know - you can upgrade from Core Duo to Core 2 Duo, the motherboard will accept either CPU. At least that's what I am doing right now

I have upgraded my T60p to a core2duo. Works great. Someone noted that you need to check the version of your motherboard, to make sure its compatible, but if so, it works. I did mine a few months back. Here is a link to the page re: the upgrade.

Also upgrade the bios

Make sure to update the BIOS before you change the processor. The BIOSs prior to 2.05 do not support the Core 2 Duo processors.

How about Core 2 Quad

?

Why is the rev. number come with MB or CPU is so important? What do they mean or represent exactly?

Does the cooling paste come with the CPU or do we have to buy it separate? What brand do u suggest? May you give me the link to that specifically in Newegg or anywhere you can fine since this would be my 1st time I change a mobile cpu

Seriously dont want to mess things up :wink:

My BIOS' upgraded to 2.11.

Thanks!

I was nervous too. I used Arctic Silver Thermal Compund. The most time consuiming/tedious part was removing all the components in the T60 that are in the way of getting to the CPU. Here is the paste...

Core 2 and Core Duo use different power planes (i.e. Voltage Regulation Modules). ONLY board rev 3 and higher have the proper VRMs to run Core 2 chips.

Forget about a quad core in a T60. Pin out is different and they put out TWICE the heat (HSF is T60 is already pushed to the limit when the cores are under load).

Google for ARCTIC SILVER 5. SVC.com usually has it for cheap (select the cheap shipping and it will probably be around $5).

Also, get the Core 2 off eBay. CPUs RARELY die, and there is no point in giving a retail store the extra money for one. Just make sure the CPU has been tested and comes with a DOA (Dead on Arrival) warranty.

I PRAY you didn't buy that from the egg. If you did, you got overcharged.

CPU-Z displays something a bit confusing to me
it says my Package is Socket 479 mPGA
My CPU is T2700, I thought it's a socket M cpu, so is socket M is the same as socket 479?

Socket M is the upcoming Socket for the Santa Rosa platform (i.e. it doesn't exist yet).

Socket 479 is correct for Core Duo/2.

Look under the different tabs. Motherboard revision will be listed under one of those.

All but a VERY FEW early T60s are rev 3.

As my understanding, Core 2 Duo also produces less heat than Core Duo, with the same clock speed, right?

stephenaron · **Posted:** Fri Apr 06, 2007 2:29 pm

NOt sure if its less heat or not, but i can tell you that the machine felt warm to the touch with both cpus.

axiom · **Posted:** Fri Apr 06, 2007 2:30 pm

I think Socket P is for Santa Rosa
socket M is for Core Duo/2
socket 478 for Pentium M

Actually, you open this and a T4x up and the sockets BOTH say socket 479 on them :wink:

The only difference is the pin out of the Core/Core 2 chips versus Pentium M (and MANY electrical differences).

Sockets are IDENTICAL (and you would not believe how many people come to me with "broken" machines because they tried to install a Core chip in a Pentium M motherboard).

how would one check the motherboard version?

Where would be the best place for one to buy a T7600 at a fair price? Thx.

Will it void my Lenovo warranty if I upgrade to Core 2 Duo myself?

If there a full-instruction manual to do this on t60?

Do I need to switch/update my BIOS to the T60 Core 2 Duo version?
(my current ver. is 2.12 Core Duo)

Do I need a 90W AC adapter for it?

Thanks

stephenaron · **Posted:** Fri Apr 27, 2007 1:48 pm

I imagine it does void the warranty. But worth it.

If you need to send the machine back, you can always swap the chip back out. I downloaded the user manual which shows how to take out the pieces necessary.

spt60 · **Posted:** Mon Apr 30, 2007 11:55 am

1. Will it void my Lenovo warranty if I upgrade to Core 2 Duo myself?
(if you swap back the chip, should it still already voided the warranty when we first opened the laptop?)

2. Do I need to switch/update my BIOS to the T60 Core 2 Duo version? (my current ver. is 2.12 Core Duo)

3. Do I need a 90W AC adapter for it, (mine right now is 65W)?

4. If there a full-instruction manual to do this on t60?

Thanks

1. Technically yes, but unless you specifically tell Lenovo that you upgraded the CPU, you should be fine. Or, as others have suggested, you can swap the CPU back to original before having Thinkpad serviced.

2. You need to have the latest BIOS, as well as to have motherboard revision 3 or above.

3. Your original AC Adapter will be fine

4. There is a hardware maintenance manual, look at the top of this board.

Can someone please post a link showing a comparison between the 2 processors : Core Duo and Core 2 Duo
Thanks

Core Quad comes in the s775 package with an IHS, so you're out of luck on that

Quote:

Compared to the desktop Core 2 Duo (Conroe), the mobile version is architecturally no different. Obviously clock speeds (both CPU and FSB) are lower because these things will be going in notebooks where power consumption is more of a concern, but other than that the architectures are identical.

Compared to Yonah, Merom has some very clear advantages; on the surface the larger L2 cache is responsible for the 140M increase in transistor count, but architecturally the improvements extend far beyond that. You can get the details from the table above or from our previous articles on Intel's Core 2 processors, but simply put Merom is wider and slightly deeper than Yonah. The slightly deeper pipeline helps increase clock speeds on Merom (which will bump performance a bit), but the added decode and execution width will increase overall performance.

Not listed in the table above are the improvements to the cache subsystem and memory accesses on Core 2 Duo. Merom features more aggressive prefetchers than Yonah, as well as Intel's Memory Disambiguation technology that allows for out of order loads. In other words, not only is Merom able to operate on more data at once, at a faster speed, but it can also get access to that data quicker.
